Value Collection 364-0044 Hex Rethreading Die M4x0.75

Product Description

The VALUE COLLECTION 364-0044 is a hex rethreading die designed to chase and restore damaged or corroded external metric threads. It is sized for M4x0.75 thread pitch and cuts in a right-hand direction, following the Metric Special thread standard. Built from carbon steel, this die delivers reliable performance for maintenance and repair tasks across mechanical, plumbing, HVAC, and electrical trades wherever metric fasteners are in use. At 0.06 pounds, it is compact enough to fit in a standard tap-and-die set or toolbox. A hex body profile allows a wrench or die stock to drive it cleanly without slippage.

This rethreading die is suited for field and shop use on M4x0.75 metric-threaded fasteners, bolts, and fittings that have sustained thread damage from corrosion, cross-threading, or mechanical wear. It is appropriate for light-gauge metric hardware common in equipment panels, motor mounts, control components, and plumbing fixture assemblies. Trades professionals use it to salvage threaded stock rather than replace damaged fasteners outright, saving time and material cost on service calls.

Key Features

• M4x0.75 thread size for Metric Special applications
• Right-hand thread direction matches standard metric fastener orientation
• Carbon steel construction provides adequate hardness for rethreading mild steel, brass, and aluminum fasteners
• Hex body profile accepts a standard die wrench or adjustable wrench for positive drive

Compatibility

Designed for use on M4x0.75 right-hand Metric Special external threads. Fits standard hex die stocks and wrenches sized for M4 rethreading dies.

Installation Notes

Rethreading dies are used by mechanics, HVAC technicians, plumbers, and electricians to restore damaged external threads. Before use, de-energize or shut off any system containing the fastener to be rethreaded. Apply cutting oil to the die and the fastener to reduce heat and extend die life. Back the die out periodically to clear chips, especially when working in blind or tight locations.
